We had small snakes, nothing over 18 inches long. They're personable, and will interact with you (I say being not sure if that would apply to the huger snakes). They ate mealworms mostly, we tried giving them a mouse once but the mouse escaped. We found it 2 weeks later, put it back in with the snakes and it was so hungry it ate one of them! Talk about turning the tables... We also had lizards and iguanas, but they really weren't interactive and didn't make good pets. (It takes more than putting an animal in a cage to make a pet). But really, all animals are of God's creation and as such we do have a tie with them. A while back I was hiking down a trail and turned a corner to see a rattlesnake sunning itself in the trail. I stood there a minute, it looked at me I at him, it was almost another mile to go around, and finally I said "I don't suppose you'd let me step over you and be on my way..?" The snake responded with a lazy shake-shake, is if it was answering "uh-uh" So I turned around and went the long way.
Snakes can be cool, but whatever you get don't just cage an animal. That's not cool.
